Sunroof humming....

[Intercooled]

Check all the rubber moldings on the sun roof exterior.
I had a Humm this past spring and it was a dried up leaf stuck in near the corner marker light . The leaf would Hum, buz at when i got on the high way. I finally got out a ladder and discovered the leaf.

I got a ladder out and cleaned the sunroof channel out completely. It still makes the humming sound. Thanks for the advice though.

I bet Ed is right. We have all been through this little experiment....

I am going through the same thing. I removed the deflector and that did not cahnge anything. I do notice that at speeds around 60, my sunroof vibrates slightly near the front of it. I believe that the movement is causing noise. Anyone else notice this?
